Notes: This genus has been reclassified and moved into the the genus Epilobium (Willowherbs). In N. America, many of these species are found in California and neighbouring dry areas. This plant thrives in sandy soil in sun with little water. It is also easy to divide into smaller clumps. Since the plant is relatively small, it can be planted at the front of a bed. Once flowers arrive, they just keep coming till long after the hummingbirds have flown south for the winter. Hummingbirds do not tend to use plants that are low to the ground. You will do more to attract hummers with this plant if it is planted in a raised bed or a pot.
